“…An adaptive nonlinear technique for controlling the angular velocity of a simple BLDC motor for mechatronic applications is proposed in [8]. The algorithm proposed by the authors involves the on-line estimation of some parameters of the electric motor model and the use of a lookup table to approximate the back e.m.f from the angular position measurement and the result of the angular speed control loop.…”

This paper presents the design flow of an advanced non-linear control strategy, able to absorb the effects that the main causes of torque oscillations, concerning synchronous electrical drives, cause on the positioning of the end-effector of a manipulator robot. The control technique used requires an exhaustive modelling of the physical phenomena that cause the electromagnetic torque oscillations. In particular, the Cogging and Stribeck effects are taken into account, whose mathematical model is incorporated in the whole system of dynamic equations representing the complex mechatronic system, formed by the mechanics of the robot links and the dynamics of the actuators. Both the modelling procedure of the robot, directly incorporating the dynamics of the actuators and the electrical drive, consisting of the modulation system and inverter, and the systematic procedure necessary to obtain the equations of the components of the control vector are described in detail. Using the Processor-In-the-Loop (PIL) paradigm for a Cortex-A53 based embedded system, the beneficial effect of the proposed advanced control strategy is validated in terms of end-effector position control, in which we compare classic control system with the proposed algorithm, in order to highlight the better performance in precision and in reducing oscillations.

“…Based on the previous considerations, a novel φτ synchronous reference frame, which is alternative to the ft synchronous reference frame, is presented in this study. It is still based on (13) but aims at preserving the magnitude of voltage and current space vectors suitably, leading to the following relationships:…”

The design of space vector control (SVC) systems suitable for flux-weakening operation of permanent magnet brushless DC machines (PMBDCMs) is presented in this study. The proposed design approach enables overcoming the critical issues arising from the non-linearities of PMBDCM voltage and torque equations; these issues derive from the trapezoidal shapes of back-emfs and affect PMBDCM constraint management significantly. The SVCs presented in this study have been developed within two different synchronous reference frames, both of which enable distinguishing torque and demagnetising current components clearly. Therefore, reference torque current component is determined in accordance with PMBDCM torque demand, while reference demagnetising current component is computed through a voltage follower PI regulator, which processes the voltage deficit detected on the DC-link. In this regard, a novel synchronous reference frame is proposed in this study, which improves PMBDCM constraint management and results into a wider constant-power speed range, but at the cost of some torque ripple. The enhanced performances achievable by SVC approaches are highlighted by numerical simulations, which regard the comparison among the SVCs and an SVC with no flux-weakening capability, at different operating conditions.

“…Therefore, one of the inputs of this block is the magnitude of this coefficient, which can be obtained from a PI speed controller, and the other input is the rotor position. In general, the major components of the torque profile are T 6 and T 12 which are functions of low-order harmonics of the back-EMF and the stator currents [9,30]. If the harmonic order of the stator current increased, the effective resistance of the motor windings will be increased, so the copper loss will be increased.…”

Brushless Harmonic current injection to the stator windings is one of the most effective methods for torque ripple reduction of brushless DC motors. Because of multi harmonic contents of the stator currents, the conventional methods based on rotational reference frame cannot be used to calculate the voltage references for voltage source inverter. sliding mode control (SMC), which has high dynamic response to track a time varying command, can be used to force the arbitrary reference current to the stator windings without transfer the motor currents to the rotational reference frame. However, the main disadvantage of SMC is that the system states cannot reach the equilibrium point in infinite time as well as has a major chattering problem. In this paper, a new control method called integral terminal sliding mode control (ITSMC) is used to overcome these drawbacks. In order to show the robustness and performance of the proposed method, this method is compared with a SMC by some simulation and experimental tests. It is concluded that the dynamic response and robustness of the proposed ITSMC method is higher than SMC and ITSMC is an appropriate method to inject the arbitrary reference current to the motor windings.
